Creating a silicone Mold
Create the Cast
I created the cast using 123D Design and an old diamond STF File from myself. I just put a Box around the diamond structure and printed it with a 3D printer afterwards.
Use a scale to get the correct mixing ration of the silicone parts
Stir the silicone mix
Pour mixture into the mold. Sadly I had a lot of bubbles.
The mold did not survive the removing process, because the silicone was very sticky.
Overall the mold turned out good, but I did not realize how bad the bubbles were.
I used the mold to cast a resin diamond structure but as you can see now the amount of bubbles was a serious problem.
So looking back at this it would have been better to apply something that the silicon is not as sticky after setting in. Also the bubbles were a huge problem which I did not realize. I saw the amount of bubbles but I did not think that the bubbles were also at the surface of the diamond structure. So it would have been better to use something like a vacuum machine to release the bubbles.
